How is current Internet infrastructure to cope with everincreasing bandwidth demands? Adding capacity to the present electronically switched network is common practice, and offers inexpensive but only temporary (bandwidth famine) relief. In the long run, it will become a necessity to rethink the technology itself. Moving to optical switching is the most viable option, but has a snake in the gra...

Hallmarks of criticality, such as power-laws and scale invariance, have been empirically found in cortical-network dynamics and it has been conjectured that operating at criticality entails functional advantages, such as optimal computational capabilities, memory and large dynamical ranges. As critical behaviour requires a high degree of fine tuning to emerge, some type of self-tuning mechanism...

Abstract—In this paper, the analytical tuning rules of IMC-PID controller are presented for the multivariable Smith predictor that involved the ideal decoupling. Accordingly, the decoupler is first introduced into the multivariable Smith predictor control system by a well-known approach of ideal decoupling, which is compactly extended for general nxn multivariable processes and the multivariabl...

Photoassociation (PA) spectrum in the presence of a magnetic Feshbach resonance is analyzed. Nonperturbative solution of the problem yields analytical expressions for PA linewidth and shift which are applicable for arbitrary PA laser intensity and magnetic field tuning of Feshbach Resonance. We show that by tuning magnetic field close to Fano minimum, it is possible to suppress power broadening...

We present a detailed model of the pathway from the retina to area 17 of the visual cortex of the adult cat. The model is used to study the orientation tuning of cortical simple cells. It is shown that a combination of unspecific inhibitory mechanisms together with input of aligned receptive fields from the LGN is able to reproduce cortical orientation selectivity and other features of cortical...

We assessed the quantitative performances of a classical method for profiling urinary organic acids: ethyl acetate extraction/oxime-trimethylsilyl derivatization/GC-MS. Twenty-seven acids were quantified on the basis of specific ions in both scan and selected-ion monitoring modes. We found that the tuning of the mass detector severely affects the calibration factors, being critical to achieve q...

This paper presents a method for tuning the scaling factors of PID type fuzzy controllers. The method tunes the input scaling factor related to change in error and the output scaling factor related to integral output of PID type of fuzzy controller using model error, error between reference model and process. Fuzzy Controller used is typical fuzzy PID type of controller in which the scaling fac...

— We introduce an analytical framework to understand the path for scaling nanophotonic interconnects to meet the energy and footprint requirements of CMOS global interconnects. We derive the device requirements for sub 100 fJ/cm/bit interconnects including tuning power, serialization-deserialization energy, and optical insertion losses. Using CMOS with integrated nanophotonics as an example pla...

Modern industrial, government, and academic organizations are collecting massive amounts of data (“big data”) at an unprecedented scale and pace. The ability to perform timely and costeffective analytical processing of such large datasets to extract deep insights is now a key ingredient for success. These insights can drive automated processes for advertisement placement, improve customer relat...

For Satisfiability (SAT) Problem there is not a deterministic algorithm able to solve it in a polynomial time. Simulated Annealing (SA) and similar algorithms like Threshold Accepting (TA) are able to find very good solutions of SAT instances only if their control parameters are correctly tuned. Classical TA’s algorithms usually use the same Markov chain length for each temperature cycle but th...
